The basic engineering will definitively include the user's requirements, basic specifications, the execution timetable and the economic evaluation.

The following jobs are defined during this phase:

• Detailed review of the concept engineering and user requirements
• Data sheets for all rooms (critical and non-critical)
• Heat load and air flow calculations for each room
• Basic water and HVAC P&ID
• Services points of use distribution
• Room layout review, including service areas
• Consumptions list
• Equipment list

Basic engineering is developed in two phase: the first comprises data acquisition and user requirement preparation and, in the second, the development of all other previously described jobs.

The approval of this engineering forms a solid base for detailed engineering development.
